Rising CO2 Lowers Nutrition Value Of Crops
2014-05-08 16:18:00| Climate Ark Climate Change & Global Warming Newsfeed
Redorbit: Grains, legumes and other crops that provide a large percentage of the world with most of their dietary zinc and iron will have dramatically reduced concentrations of those nutrients by 2050 due to rising levels of atmospheric carbon dioxide, according to a new study led by Harvard School of Public Health (HSPH). The researchers studied multiple varieties of wheat, rice, field peas, soybeans, maize and sorghum grown in fields with atmospheric carbon dioxide levels comparable to those expected...

Rising carbon dioxide levels affect nutrients in crops, study says
2014-05-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
LA Times: The increased concentration of carbon dioxide that comes with climate change could mean some basic food plants will carry lower concentrations of iron and zinc -- and deficiencies of those nutrients are already a "substantial global public health problem," scientists reported Wednesday. The edible portions of many of the key crops for human nutrition have decreased nutritional value when compared with the same plants grown at the present ambient [carbon dioxide]. - Study published in the journal...

Rising Carbon Dioxide Levels Zap Crops of their Nutrients

Nature World: Rising carbon dioxide (CO2) levels are zapping greens and legumes of their nutrients, according to a new study in the journal Nature. Pictured: Researchers using the Free Air Concentration Enrichment (FACE) system at the University of Illinois to simulate future atmospheric conditions. Rising carbon dioxide (CO2) levels are zapping greens and legumes of their nutrients, according to a new study in the journal Nature. Atmospheric CO2 concentrations are currently approaching 400 parts per million...

Climate change making food crops less nutritious, research finds
2014-05-07 19:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Rising carbon dioxide emissions are set to make the world's staple food crops less nutritious, according to new scientific research, worsening the serious ill health already suffered by billions of malnourished people. The surprise consequence of fossil fuel burning is linked directly to the rise in CO2 levels which, unlike some of the predicted impacts of climate change, are undisputed. The field trials of wheat, rice, maize and soybeans showed that higher CO2 levels significantly reduced the...

High CO2 Makes Crops Less Nutritious
2014-05-07 13:02:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: Crops grown in the high-CO2 atmosphere of the future could be significantly less nutritious, a new study published today in Nature suggests. Based on hundreds of experiments in the field, the work reveals a new challenge as society reckons with both rising carbon emissions and malnutrition in the future. Scientists generally predict that crop yields could fall in a warmer world-though higher atmospheric CO2 by itself should raise yields, as plants find it easier to extract CO2 from the air to...
